ELECTRICAL CALL. SYSTEM.

SPECEEECATION forming part of Letters Patent No. 356,850, dated February 1, 1887.

` A pplicalion filed Octnlierl, 1886. Serial No. 215,088. (No model.)

To @ZZ wimmzt may concern.:

Beit known that l, JoHNDnvID Pnncnnr, a citizen of the United States, residing at Denver, in the county of Arapahoe and State ot' Colorado, have invented a new and useful Iznproveinent in Electrical CallSystenis, of which the following is a specification.

My invention relates to an improvement in electrical call systems for Vhotels and other buildings; and it consists in the combination of the niain lines of conductors in the various doors and halls of thehuilding, each connected in open circuit with an annunciator, and local lines proceeding from the various rooms and connected to the main lines, and signals or indicators, each having a spring-actuated signal door or arm, a detect to secure the same when closed, and a lever connected with one of the local lines and adapted to simultaneously trip the detent and close the circuit, and thereby sound the annunciator and also display the signal. r

My invention further consists in the peculiar construction and combination of devices, that Will he more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a diagram illustrating the arrangement of my electrical call system in a hotel or other huilding. Fig. 2 is a detailed perspective view of one of the circuit-@losers and mechanical signals with the saine closed. Figs. 3 and el are views illustrating ainodified form of the same.

In the diagram, A represents a series of electrical annunciators, there being one for each hall or section in the building. I herein show six of such annuuciators, there being that many sections or halls in the diagram; but it will be understood that the number of annunciators will he varied to suitthe requirements of each particular case.

B represents a battery or other source of electricity. From one pole of the battery a Wire, C, intersecting the halls 0r sections of the building, is run. From the opposite pole extends a Wire, D, which is connected to one pole of the electric magnets in the annunciators o b c el cf by branch Wires o" b c' d ef, respectively.

a? represents a main line, the Wires of which are located in one of the halls or sections of the buildinfr. One end ofthe said line is connected to the wire C, and the other lend thereof is connected to the electromagnet in the annunciator c.

a. represents a series of local lines, which extend from the roonxsin the hall or section in which the line of is located and are connected to the said line, as shown. In each local line is included a circuitcloser, a", and the said circuit-closers are nornially open.

Freni the foregoing it will he readily seen that each room or station in the hall or section at' is connected in open circuit with the battery and the annnnciator c, and that when one of thecircnitclosers o* is caused to close the circuit the annunciator o will be sounded and will indicate that a person in one of the rooms in the hall or section a is calling.

b2, 62d, 0"', and f2 represent main lines lo cated in the remaining halls or sections of the building, and are each connected to the Wire C and to the annunciators b, c, d, e, andf, respectively. The said main lines have their respective local lines bccl'ca, andf3 provided with circuit-closers b,c",d*,e, and j", as shown.

In order to enable the person who answers the call from any hall or section oi the building to ascertain the room or station in the said hall or section Afrom which the call was sounded, I combine with each circuitcloser a signal which is adapted to be automatically displayed by the circuit-closer When the latter is operated. In Fig. 2 I illustrate one means by which this feature of my invention may he carried into effect.

D represents a block or case, to Which is hinged a door or arin, E, that constitutes the signal, and is painted red or any other appropriate bright color that can he readily discerned. To the side of the block or case against which the door or arm closes is secured a spring-catch, F, which is adapted to engage the free side of the door or arm and lock the saine when closed against the block or case.

G represents a lever of the rst class, which is pivoted to the block or case. A pull cord, rod, or Wire, H, is attached to one end of the lever, and passes through an opening in the block or case and enters a room or station, and is provided with a handle or tassel, I. The other end of the lever is adapted to strike IOO against the spring-catch and cause the same to release the door or arm when the cord is pulled, and aspring, K, bears against the said door or arm, the function of the said spring being to throw the said door or arm open to display the same when the cord is pulled.

The block or case is secured to the outer side of the doorway or to any other conven ient place in the hall, and the cord, rod, or wire extends through an opening made in the door, transom, or wall into the room, as previously described. The springcatch F forms the terminal of one of the wires of a local line such as heretofore described, and the lever forms the terminal of the other wire of the said local line, the said spring-catch and lever thereby constituting the circuit-closer. A spring, L, bears against the lever, the function ot' the said spring being to normally move the lever from the springcatch, so as to open the circuit.

The operation of theinvention will be readily understood. When a person in the room wishes to callan attendant, he grasps the cord, rod, or wire and pulls upon the same, thereby closing the circuit and sounding one of the annunciators, which indicates the hall or scction in which the room is located. As soon as the lever reaches the spring-catch the latter releases the door or arm, which instantly swings open, and thus indicates to the attendant the precise room in the hall or section from which the call was sounded. l/Vhen he answers the call, he closes the door or arm to its normal position, and thus withdraws the signal.

In Figs. 3 and 4 lillustrate a modied form of the local signal and circuit-closer, in which M represents a plate forming one terminal of the local line, and N represents a plate forming the other terminal thereof. O is a sliding` detent adapted to engage the door when the' latter is closed, the said detent being in contact with the plate M andl normally out of contact with the plate N. P, has one end attached to tlie detent, and a spring, R, bears against the other end of the lever. S represents a turning rod, which projects through the wall to which the circuit- A pivoted lever, i

closer is attached, and has a handle or ring on its inner end. By turning the said rod the lever is caused to move the detent rearwardly, so as to release the spring-actuated door or signal and come in contact with the plate N, thereby closing the circuit and sounding the alarm, as before.

I do not desire to limit myself to the precise construction heretofore described, as it is evident that modifications may be made therein without departing from the spirit of my invention.

Having thus described my invention, I claim- 1. The combination, with the door or arm, of the detent to engage the same, the electrical circuitclosing` lever to trip the detent, and the spring` to normally movethe said lever from the detent, substantially as described.

Y 2. The combination, with the door or arm constituting the signal or indicator and having the actuating-spring, of the detent to en gage the said door or arm when closed, the electric circuitclosing lever to trip the detent, and the spring to normally move the said lever from the detent, substantially as described.

3. The combination of the spring-actuated horizontallyopening door or arm E, the detent to engage the same when closed, the pivoted spring-actuated lever to trip the detent and. close. the circuit, and means to turn the said lever, substantially as described.

4. The combination ot' the main lines of conductors, each connected in open circuit with the battery and with an annunciator, the local lines connected to the main lines, and the signals or indicators, each having the spring-actuated signal door or arm, the detent to secure the same when closed, and the lever connected with thelocal line and adapted to simultaneously trip the detent and close the circuit, substantially as described.

In testimony that I claim the foregoing as my own I. have hereto aixed my signature in presence of two witnesses.

JOHN DAVID PEAGHEY.
